摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

摘要： Techniques for allocating and mapping resources in a wireless communication system are described. The system may use hop-ports to facilitate allocation and use of subcarriers. In one aspect, the hop-ports may be partitioned into multiple subzones, with each subzone including a configurable number of hop-ports. The hop-ports within each subzone may be permuted or shuffled based on a permutation function. After permutation, the hop-ports in all subzones may be mapped to the subcarriers based on local or global hopping. In another aspect, a set of hop-ports may be mapped to a set of subcarriers. A hop-port may be mapped to an unavailable subcarrier and may then be remapped to another available subcarrier. In yet another aspect, a set of hop-ports may be mapped to a set of subcarriers distributed (e.g., evenly) across all subcarriers but avoiding subcarriers in a reserved zone.

摘要： Beacon symbols are sent periodically from the base stations in an OFDM system. The entire power of the base station, or a large portion of it is concentrated in these symbols, thus they are very easily recognized by the mobile stations. The frequencies upon which these symbols are transmitted and the time at which they are transmitted communicates information such as the base station/sector identity and the preferred carrier of the given base station/sector to the mobile station. In order to avoid collision between the beacon symbols of different base stations and sectors, the beacon symbols from different base stations/sectors are transmitted at different symbols times and on different subcarriers.
摘要翻译：信标符号在OFDM系统中从基站周期性地发送。基站的整个功率或其大部分集中在这些符号中，因此它们被移动台非常容易地识别。发送这些符号的频率和它们被发送的时间将诸如基站/扇区标识和给定基站/扇区的优选载波的信息传送给移动站。为了避免不同基站和扇区的信标符号之间的冲突，来自不同基站/扇区的信标符号在不同的符号时间和不同子载波上发送。

摘要： Systems and methodologies are described that provide support for signal acquisition in wireless communication systems that utilize half-duplex communication in the presence of asynchronous sectors. Forward link and reverse link superframes can be structured such that a given frame position in a superframe alternates between forward link communication and reverse link communication for a particular half-duplex interlace. More particularly, an odd number of frames can be grouped into respective forward link and reverse link superframes, from which frames can be assigned to a first half-duplex interlace and a second half-duplex interlace in an alternating fashion. By varying the communication link used by a half-duplex interlace at a given frame location, terminals operating on a single half-duplex interlace can detect asynchronously operating sectors irrespective of the transmission timeline of such sectors.
摘要翻译：描述了在存在异步扇区的情况下利用半双工通信的无线通信系统中的信号获取的支持的系统和方法。可以构造前向链路和反向链路超帧，使得超帧中的给定帧位置在特定半双工交错的前向链路通信和反向链路通信之间交替。更具体地，奇数帧可以被分组成相应的前向链路和反向链路超帧，从该帧可以以交替的方式将帧分配给第一半双工交错和第二半双工交错。通过改变在给定帧位置处的半双工交错使用的通信链路，在单个半双工交错上操作的终端可以检测异步操作扇区，而与这些扇区的传输时间线无关。

摘要： Providing for base station (BS) acquisition in semi-planned or unplanned wireless access networks is described herein. By way of example, a signal preamble can be dynamically allocated to wireless signal resources, such that the preamble is scheduled to different resource(s) across different cycles of the signal. Dynamic allocation can be pseudo-random, based on collision feedback, or determined by a suitable algorithm to mitigate collisions from a dominant interferer. In addition, dynamic scheduling can be particular to a type of BS to significantly reduce collisions from BSs of disparate types. In at least one aspect, a preamble resource can be subdivided into multiple frequency sub-carrier tiles. Control channel information can be transmitted on each tile of a group of such tiles, further mitigating effects of a dominant interferer on a subset of the tile group.
摘要翻译：这里描述了在半计划或非计划无线接入网络中提供基站（BS）获取。举例来说，可以将信号前导码动态分配给无线信号资源，使得在信号的不同周期内将前导码调度到不同的资源。动态分配可以是伪随机的，基于碰撞反馈，或者由合适的算法确定以减轻来自主要干扰源的冲突。另外，动态调度对于一类BS来说是特定的，以显着减少来自不同类型的BS的冲突。在至少一个方面，前导码资源可以被细分成多个频率子载波瓦片。控制信道信息可以在一组这样的瓦片的每个瓦片上传输，进一步减轻主要干扰对瓦片组的子集的影响。

摘要： Techniques for sending control information in a wireless communication system are described. A control segment may include tiles, and each tile may include a number of transmission units. A number of control resources may be defined and mapped to the transmission units for the control segment. For symmetric mapping, multiple sets of control resources may be formed, and each batch of L consecutive sets of S control resources may be mapped to S transmission units at the same location in the L tiles. For localized mapping, each set of S control resources may be mapped to a cluster of S adjacent transmission units in one tile. For distributed mapping, each control resource may be mapped to one transmission unit in one tile. For diversity, each control resource may be mapped to multiple (e.g., three) transmission units in at least one tile.
